In the trainer I flew there was a block of rectangular warning 

lights that indicated things like canopy open, alternator fault 

etc.  You could depress the lense of the warning lamp to light 

and thus test the bulbs.  Does anyone know of a source of such 

- preferrably compatible with B&C's LR-3 Alternator Controller 

OV lamp feed.



Thx in advance for any suggestions...

Gerry -



NKK has a line of lamps that are LED's. I installed two B&C voltage  

regulators (dual battery Z-14) and wired them to their own low voltage  

lamp. They work great. There is no press-to-test feature, but you could  

design a circuit to test them all at once. I did not feel that the  

press-to-test feature is all that critical with LED's and their inherent  

longevity. Also for the regulators, you will get a light as soon as you  

turn the battery switch on for each circuit. If they do not come on, you  

should not go anywhere until you know why this is so. Same for oil  

pressure, canopy open. For boost high and low, we check for fuel pressure  

before start and check the light then.



I have the annunciator circuit on a .pdf if you need it. The resistor  

values for the LED's are a little different than the ones Bob shows in a  

diagram he published. Check this for a view of the annunciator panel:

The low volts are off because we have number 2 battery on at about 13.1  

volts and are checking the crossfeed function. Normally you would see the  

external power light on during our full testing as well, and probably no  

crossfeed light.



Cheers,

Gerry, if you are happy with regular incandescent or LED lamps (like 

John Schroeder's), and want a handy circuit to drive them, allow for 

dimming and lamp test with an *external* pushbutton, look at the IL-4A 

or IL-12A at www.vx-aviation.com



Thanks,
